Possible side effects of Enbrel include reactions at the injection site, headaches, and dizziness. Most people, however, have no problems. If they occur, side effects are usually minor and easily treated. However, if you experience more serious side effects, such as a numb or tingling feeling, changes in vision, or chest pain, you should report them to your healthcare provider right away.
